Principle Operation of High temperature Switch for Fly Ash
The probe of the Admittance Switch forms one plate of a capacitance circuit, with the vessel wall making the second plate. The dielectric constant of the product between the probe and the vessel wall will cause a change of capacitance as the level approaches the probe. The change is detected, amplified and used to switch a relay for indication or control purposes. A special circuit is used to ignore product build-up between the sensing probe (active element) and guard, and also between the guard and vessel wall.
Function of High temperature Switch for Fly Ash
The Gladiator Admittance Smart Switch is point level switch for liquids, solids and powders. The unit is suitable for a broad range of products and dielectric constants up to high temperature of 450oC (842oF).
